Embedded pdfs with Reader X and Internet Explorer 8 sporadicly have error "103:103"

After upgrading to Acrobate Reader X I am having trouble viewing embedded pdfs in Internet Explorer 8. It seems to happen spordicly but I can get the error to happen consistently after viewing at most 20ish pdfs. I have reproduced the problem on 3 computers so far.

A gray square shows where the pdf should be and internet freezes. After 30-60 seconds a error dialog shows up saying "There is a problem with Adobe Acrobat/Reader. If it is running, please exit and try again (103:103)".

I haven't found any refrences to this on the internet yet, has anyone exprienced this and had any luck dealing with it?

Adobe Reader Version:  10.0.0

Internet Explorer Version: 8.0.6001.18702C0
